A saddle-stitched A4 notebook, 16 pages - SONY CD player catalog for February 1987, arranged in three tiers: the ES series (flagship CDP-555ESD at ¥150,000 - “New Reference” replacing the 553ESD, plus external DAC DAS-703ES at ¥250,000), the home range from CDP-510 to CDP-M30, and a new arrival - the five-disc “CD Roulette” CDP-C5M. The central technical spread lays out four principles of the “Sony Intelligent CD Player”: separate component layout, 8x digital filter, predictive S-Servo and Table of Contents control. The opening spread “Voice of CD” shows foreign models in knit sweaters with the slogan: “now the CD player has begun to speak about music.”
- 高精度デジタルフィルター - High-Precision Digital Filter - 8x oversampling with digital filter instead of analog; eliminates quantization staircase artifacts and reduces demands on the analog stage
- Sサーボ - S-Servo - predictive disc tracking system; anticipates wobble instead of reactive correction, reducing vibration in the drive mechanism
- デジタル出力 - Digital Output - coaxial and optical digital outputs (S/PDIF) on flagship CDP-555ESD and CDP-333ESD; allows passing the uncompressed stream to external DAC DAS-703ES
- リニアフェーズフィルター - Linear Phase Filter - linear phase analog low-pass filter at output; eliminates phase shifts in the upper audio range
